Professor of Geosystem Science, Leader of ECI Climate Research Programme, University of Oxford

Myles Allen is Professor of Geosystem Science in the Environmental Change Institute, School of Geography and the Environment and Department of Physics, University of Oxford. His research focuses on how human and natural influences on climate contribute to observed climate change and risks of extreme weather and in quantifying their implications for long-range climate forecasts.

Myles has served on the Intergovernmental Panel on Climate Change as Lead Author on Detection of Climate Change and Attribution of Causes for the 3rd and 5th Assessments in 2001 and 2013, as Review Editor on Global Climate Projections for the 4th Assessment in 2007, and as

He proposed the use of Probabilistic Event Attribution to quantify the contribution of human and other external influences on climate to specific individual weather events; the use of cumulative carbon dioxide emissions to predict peak warming; and leads the project, using distributed computing to run the world’s largest ensemble climate modelling experiments.
